Actors Donald Faison, Neil Patrick Harris, Patrick Dempsey and Kate Walsh have teamed up to star in health insurance company Cigna's new campaign, TV Doctors of America.

The personalities, all of whom have played doctors in TV shows including Scrubs and Grey's Anatomy, are seen encouraging people to 'take control of their health' by going for annual check-ups and knowing their biometric numbers, and Stephen Cassell, Cigna's Vice President of Global Branding, commented 'The talented TV Doctors cast is personally committed to helping people improve their health, and they're helping us use humour to bring an urgent health message to the American public in a light hearted way'.
